Routine maintenance of unsealed roads using best practice standards is generally more cost-effective than allowing roads to derate to levels requiring substantial works. The guide is educational and advisory in nature and provides information on best management practices. Any legislative or

Unsealed roads should have at least a slight longitudinal grade to allow free surface drainage and to avoid excessive ponding within wheel tracks. Generally the grade of a track should be less than 10° (17.5%). Short lengths of steeper grades may be needed to negotiate difficult

The assessment of unsealed roads in South Africa has, up to now, been done on an ad hoc basis with a variety of individual standards and has produced highly subjective results. A standard visual assessment manual has been developed to provide a single, unified objective system of unsealed road evaluation in South Africa and southern Africa.

of unsealed roads were rated by people hired to spend the summer evaluating roads and road features—sealed roads, unsealed roads, culverts, signs, and cattle guards. Because of the extensive nature of these counties' unsealed road networks, quick visual condition assessments had to be made. Training and guidance materials were 2). For this ).

U4 (AADT <20) – A moderate – low standard unsealed application that incorporates predominantly natural gravel as a wearing course a minimum of 150mm thick U5 (<10) – A low standard application that incorporates the existing subgrade material once cleared of vegetation and undesirable material Whilst the pavement thickness is paramount to the successfulness of a pavement structure ...

Accounting for unsealed road pavements. Our Council undertook a re-valuation of our road assets in 2011/12 and as part of this process took a closer look at unsealed roads. Our unsealed roads are componentised into 3 categories; formation, pavement and gravel wearing surface.

unsealed road Take into account the standard of the current geometric design of the unsealed road. This includes vertical/ horizontal alignment, sight distance, etc. Safety features of the unsealed road include actual/potential accidents. 0 – Poor horizontal, vertical alignment and width <5m 1 – Poor width <5m (Good horizontal and/or vertical

The purpose of the Unsealed Road Maintenance Plan is to establish a management system for Council to inspect, maintain and repair its public roads based on policy and operational objectives having regard to available resources.
